Tropical Easterly Waves Over Costa Rica and Their Relationship to the Diurnal Cycle of Rainfall

Geophysical Research Letters, Volume 50, Issue 20, 28 October 2023., 2023
Abstract Using an index of tropical easterly wave (TEW) activity derived from spacetime‐filtered outgoing longwave radiation, we construct composites of long‐term hourly surface meteorological observations and morningtime sounding data collected near San José, Costa Rica to investigate how TEWs affect the diurnal cycle of rainfall over land.
